WIRE-COUPLING.

SEEGIFIGATION forming part of Letters Patent- No. 515,420, datedFebruary 27, 1894.

Application filed March 13, 1893. Serial No. 465,834. (No model.) i

To all whom it 'may concern.-

Be it known that I, DAVID A. BYERS, a citizen of the United States ofAmerica, residing at Denver, in the county of Arapahoe and State ofColorado, have invented certain new and useful Improvements inire-Couplings; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled,in the art to which it appertains to make and use the same, referencebeing bad to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

My invention relates to improvements in couplings adapted for use inuniting the sections of wires composed of single strand as trolleywires, or of wire ropes or cables composed of many strands, twisted orotherwise, assembled according to the purpose they are intended toserve.

The object of my invention is to provide a coupling which shall besimple in construction, economical in cost, reliable, durable andefiicient in use.

To this end the invention consists of the features hereinafter describedand claimed, all of which will be fully understood by reference to theaccompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure l is a longitudinal section taken through thecoupling. Fig. 2 is a plan view of the removable plate. Fig. 3 is atransverse section taken through the coupling.

Similar reference characters indicating corresponding parts or elementsin the several, views, let the numeral 5 designate the body of thecoupling, composed of a continuous tube into which the extremities ofthe cable to be coupled are drawn.

I use the term cable in this specification in its broad andcomprehensive sense to designate a single wire, or a rope composed of aplural number of strands, twisted or otherwise, assembled in intimaterelation.

The openings in the extremities of the tubular part 5 are cylindrical asshown at 5, while from the cylindrical portions the opening expands asshown at 5 and merges into a central chamber 5 where it attains itsgreatest diameter. This coupling shell is provided with an opening 6,leading to chamber 5. This opening is closed when the joint is formed,by a plate 7 apertured to receive screws 8 which pass through thechamber 5 and enter. threaded apertures 9 formed in the shell of thetube. The joint is formed by drawing the extremities to be coupledthrough the tube and out through the central opening 6, after whichthese extremities are enlarged or upset as shown at 10 to fit theenlarged apertures 5 of the openingin the shell. The plate 7 is thenplaced in position and fastened when the joint is complete and secure,as the enlarged or upset extremities 10 cannot be drawn through thesmaller cylindrical openings 5. I

Having thus described my invention, what I claim is A coupling composedof an integral open ended tube enlarged interiorly and a detachableplate covering an opening leading to the central chamber, substantiallyas described.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID A. BYERS.
